Researchers develop ultra-simple method for creating nanoscale gold coatings
Date:6/16/2010

Troy, N.Y. Researchers at Rensselaer Polytechnic Institute have developed a new, ultra-simple method for making layers of gold that measure only billionths of a meter thick. The process, which requires no sophisticated equipment and works on nearly any surface including silicon wafers, could have important implications for nanoelectronics and semiconductor manufacturing.

Sang-Kee Eah, assistant professor in the Department of Physics, Applied Physics, and Astronomy at Rensselaer, and graduate student Matthew N. Martin infused liquid toluene a common industrial solvent with gold nanoparticles. The nanoparticles form a flat, closely packed layer of gold on the surface of the liquid where it meets air. By putting a droplet of this gold-infused liquid on a surface, and waiting for the toluene to evaporate, the researchers were able to successfully coat many different surfaces including a 3-inch silicon wafer with a monolayer of gold nanoparticles.

"There has been tremendous progress in recent years in the chemical syntheses of colloidal nanoparticles. However, fabricating a monolayer film of nanoparticles that is spatially uniform at all length scales from nanometers to millimeters still proves to be quite a challenge," Eah said. "We hope our new ultra-simple method for creating monolayers will inspire the imagination of other scientists and engineers for ever-widening applications of gold nanoparticles."

Results of the study, titled "Charged gold nanoparticles in non-polar solvents: 10-min synthesis and 2-D self-assembly," were published recently in the journal Langmuir. Read the journal paper at: http://dx.doi.org/10.1021/la100591h

Whereas other synthesis methods take several hours, this new method chemically synthesizes gold nanoparticles in only 10
